4 < 2x -15
19< 2x
9.5 < x
Unless you meant...
4 /2x -15<0
Add 15:
4/2x < 15
Multiply by 2x:
4 < 30x
2/15
4 / 2x-15 < 0
Add 15 to both sides
4 / 2x < 15
multiply thru by 2x
30x > 4
x > 2/15
.

solve 4/2x - 15 = 0
4/2x = 15
2/x=15
1/x = 15/2
x = 2/15
x<2/15

2/4 * 4/2x < 15* 2/4
x < (15*2)/4
x< 7.5

add 15 to each side
multiply each side by 2x
divide each side by 30 (2 times 15)x
